Courier by Switch Suite: Privacy Policy

Last updated: November 11, 2026

Courier by Switch Suite ("Courier", "the app") is an email app published by Switch Suite. It connects your phone directly to your own email provider. Switch Suite has no server for Courier and doesn't receive your email, your password or any other personal data.

Your mail and your password

When you add an account, Courier keeps the following only on your device, in the app's private storage:

• your email address, name and signature;
• the password or app password for your mail server;
• the server settings.

Courier uses them to connect to your own mail provider's servers (for example Gmail over IMAP and SMTP) to download, send and manage your mail. Your messages and attachments go between your phone and your provider and are stored on your phone so you can read them. New accounts must use an encrypted connection (SSL/TLS or STARTTLS).

Setting up an account

To find your provider's server settings, Courier first looks your email domain up in a list of providers built into the app, on the device. If your domain isn't in that list, Courier asks your own domain for its settings, at `https://autoconfig.<your domain>/…` and `https://<your domain>/.well-known/autoconfig/…`, without sending your email address. If neither works, you enter the settings yourself. Courier doesn't send your domain or address to any other lookup service.

Contacts

If you allow it, Courier reads the contacts on your phone to suggest recipients and show names. Contacts are read on the device and are never uploaded by Courier. An address leaves your phone only when you send a message to it.

Get new mail instantly

If you turn this on, Courier keeps a connection open to your mail server so new messages arrive quickly. The connection goes only to your mail provider.

Images and links in messages

Remote images are blocked unless you choose to load them. Loading them contacts the servers that host those images, as any email app does.

Purchases

Courier Pro is a one-time in-app purchase made through Google Play. Google processes the payment; Switch Suite never sees your payment details. To check whether you own Pro, the app asks Google Play on your device, and keeps only "Pro: yes/no" on your device. Google's Play Billing Library, which the app uses for purchases, communicates with Google Play and may send diagnostic information about the purchase process to Google. Google's handling of that information is described in the Google Privacy Policy: https://policies.google.com/privacy

What Courier doesn't do

Courier has no ads, no analytics, no crash reporting and no Switch Suite account. Diagnostic logs are stored only on your device, and only if you turn them on; they leave your phone only if you choose to share them.

Deleting your data

Removing an account in Courier deletes that account's data from your phone. Uninstalling Courier deletes everything it stored. Mail on your provider's servers is managed by your provider.

Children

Courier is not directed at children.

Changes

If this policy changes, the new version will be posted at https://switchsuite.io/privacy/courier/ with a new "Last updated" date.
